Overview

History & significance

Gaer Roman Site is a Roman auxiliary fort located near Brecon in Powys, Wales, dating to the late first century AD. The fort was established as part of the Roman military infrastructure for controlling the upland regions of South Wales following the conquest campaigns of the 70s AD. The site preserves substantial earthwork remains including the characteristic playing-card shaped defensive ditches and ramparts typical of Roman forts of this period. Gaer functioned as a garrison for auxiliary troops and represents an important example of Roman military architecture in the Welsh borderlands, guarding routes through the Brecon Beacons and maintaining Roman control over the local population.
